Used NANOMETRICS / BIO-RAD / ACCENT Quaestor Q8 #9229790 for sale

NANOMETRICS / BIO-RAD / ACCENT Quaestor Q8 is a mask and wafer inspection equipment designed to inspect etched masks and wafers used in photolithography. The system is built with an 8-inch wafer size supported chamber capable of high-magnification imaging of masks and wafers. It has a dual unit design that allows two complete systems in one chamber, with Fab 2, optically correct, achromatic objectives that reduce distortion and create a high quality image from the highest resolution and best contrast available. The optics of ACCENT Quaestor Q8 are optimized to maximize imaging and detectability of features of any size, shape, material, and orientation in any type of mask or wafer without distortion. It comes with a 5-axis hybrid translation/rotation stage capable of unrestricted motions enabling the inspection of over-sized wafers or those with very complex geometries. The machine is equipped with a pair of Dalsa 4 megapixel monochrome cameras that capture images of large areas with a variety of light sources including LED and halogen. The cameras also support feature-rich software that allows users to measure, document, and report on any anomalies or defects they detect. BIO-RAD Quaestor Q8 houses a sophisticated hardware and software tool that maximize its performance and accuracy in analyzing any given mask or wafer. It is designed to enable automatic image acquisition, product alignment, defect identification and classification. It incorporates powerful algorithms to segment, compare, and analyze data such as the number of missing/added features, narrowing-down the defect analysis and reduce false positives. The asset also features pattern matching capabilities that allow users to instantly detect and compare patterns between different masks or wafers, as well as the ability to view images in cross-section for enhanced analysis. Overall, NANOMETRICS Quaestor Q8 provides a comprehensive inspection model for mask and wafer analysis. Its advanced optics are designed to ensure the highest quality and most accurate imaging, while its sophisticated hardware and software equipment ensures a high level of automation and precision. These features enable users to quickly and easily detect and classify anomalies on any type of mask or wafer.
